Cannot launch Magic Pack since updating:
I've seen references to "invtweaks/InvTweaksMod : Unsupported major.minor version 51.0" for other packs, but not for Magic Pack. I've tried "force update"; same result. I'm on Max OS 10.6.8, so Java 7 is not an option.
If this is a known issue and a fix is not yet available, could someone point me to the thread to watch for updates? My search-fu has failed me thus far. Thanks!
